Wow... MPALC and MPSIM.  Where have you BEEN, dude?

If I were you, I would download MPASM (the assembler that replaced
MPALC a few years ago) and MPLAB (which includes a Windows-based
simulator that's much more powerful and MUCH easier to use than
MPSIM).  Both are available for free from Microchip's web site:

By the way, your code is fine.  I vaguely recall a bug in an ancient
version of MPSIM that resulted in the behavior you describe.
